CARBURETER.

SPECIFICATION forming part of Letters Patent No. 671,052, dated April 2,1901.

Application filed October 5, 1900. Serial No. 32,129I (No model.)

To all whom it may 0071/0071711:

Be it known that I, FRANZ KELLER KURZ, a citizen of the Republic ofSwitzerland, residing at Lucerne, Switzerland, have invented certain newand useful Improvements in Apparatus for Carbureting Gas by the Vapor ofLiquid, of which the following is a specification.

This invention relates to an apparatus for carbureting gas with thevapor of an appropriate liquid, particularly applicable to themanufacture of air-gas-that is to say, of a combustible mixture made bypressing air over a porous mass saturated with gasolene or the like. Asis known, such a mixture may be used as a substitute for coal-gas.

The essence of the invention resides in the fact that the supply ofgasolene is automatically regulated to correspond with the consumptionof the gas. The compressed air necessary for working the apparatus isderived either from a holder or from au appropriate blower', which maybe set in action at the beginning of the gas consumption and supplies acurrent of air to the carbureter. In the latter case the whole workingmay be automatic.

By way of example there is shown in elevation, partly in section, in theaccompanying drawing an apparatus constructed according to thisinvention.

The carbureter a is in this instance counterbalanced on an ordinaryweigh-bridge.

The counterweight mechanism is shown to be composed of a platform S10,supported near one end upon the knife-edge S8 of a lever s', which is inturn supported upon knife-edge S11. The platform and lever arerespectively connected by rods S2 s3 with the scale-beam,

partition e, which, however, extends only across the interior of theporous cylinder. The air enters into the interior of the lowercompartment of the cylinder through the pipe fand passes through theporous wall into the space between the sheath and the cylinder, andthence it again passes through the porous wall into the uppercompartment and finally flows out through a pipe g. The connection ofthe pipes f and g with the fixed parts of the pipe which conducts theair to the apparatus and that which leads away the gas, respectively,are made telescopic with liquid seals 7L 'L' in order to allow freemovement of the carbureter. The seal t is connected to post A by arm t"and collar 112. A draw-O cock i3 serves to remove any possibleaccumulation of liquid from the gas-discharge pipe t4. The seal h hasthe air-pipe h2 and is connected to the vertical post A by arm t'* andcollar h5. A small coil h4, having cock hlserves to discharge anypossible accumulation of gasolene from the carbureter. The two parts ofthe carbureter-sheath are also connected by a liquid seal d'.

Vertically above the carbureter is supported a gasolene-tank k, adaptedto be filled through Siphon-tube 7.06 and of a capacity sufficient for,say, a twodays supply. The tank 7c is connected to post A by arm 7c' andcollar 7a2. The arm k is, by brace 7c3 and bent arm 7a4, connected to asecond collar h5 of post A, so that any vertical displacement of tank7.o is prevented. At the bottom of the tank is a pipe l, closed at itsupper end by a valve m and opening at its lower end in a vessel n,supported on the carbureter. The connection between the pipe 'Z and thisvessel is a water seal. The valve m is attached to a wire or rod m',which at a certain height of the carbureter bears at its lower end onthe bottom of the vessel n. This vessel is, through pipe g, connected tocarbnreter d, and thus rises and falls together with the same. A bentSiphon-tube o leads the gasolene from the vessel 'a to the carbureter.The height of the column of liquid which remains in this Siphon-tube ois so chosen that a pressure in the carbureter will not cause gas toflow by way of the vessel n. From the tube o the gasolene Hows into agutter ot on the conical cover of the carburetor-cylinder b, which gut-IOO if. La'

ter, as well as the cover, is coated with porthence is uniformlydistributed over the whole surface of the cylinder-a result which isaided by the packing between the rings of which the cylinder iscomposed.

The tank 7c is closed above and is in cornmunication with a bag p, whichreceives the y -part of the gasolene the carbureter becomes gas or vaporexpelled when the tank 'is filled. The filling is effected through astop-cock funnel froina vessel q, also provided with a cock g3 and whichdischarges the gasolene into tank It through tube k6. The vessel q isconnected to post A by arm q/ and collar q2. The cover of the tank 7calso carries a glass tube r, in which is the end of a wire m2, carriedby the valve m, the position of this end y in the tube serving toindicate the position 2 A float with an indicator, also extending intothe glass tube, shows the level 1 of the valve.

of the liquid in the tank it. `The vessel n is provided at its lowerpart with a draw-offl` cock s.

The apparatus works as follows: The tank k is rst filled with gasolene.There being no weights on the counterbalancing-pan of the weigh-bridge,the carbureter is in its lowest position and the valve-rod m is out of;

At the edge of the cover it falls indrops into the gutter a2 of the upper- -1 most ring b and descendsgradually through the pores of such rings, while the rings c Will Byplacing weights on ihe scale-pan the carbureter is raised and the valvem is lifted to a certain i cause a uniform distribution of the liquid.In this Way the weight of the porous cylinder is increased, so that thecarbureter sinks and the valve m closes. By proper adjustment of theweights the amount of gasolene admitted may be regulated to the properproportion for the air. If it is undesirable that the whole of thegasolene should enter the carbureter, a portion can be drawn off fromthe vessel n by the cock S. As the air passes through the carbureter andcarries away a lighter and is raised until it opens the valve and admitsmore gasolene. While gas is being produced the apparatus and weightsshould be in equilibrium, which may be observed on the indicator of theweigh-bridge.

The degree of carb u reting may be varied i-n this apparatus accordinglyas illuminating or heating gas is required.

I claim- 1. In a carbureting apparatus, the combination of acounterbalanced porous gasilier, with an air-inlet pipe, agas-deliverypipe, and a gasolene-tank communicating therewith, and with a valvebetween the gasolene-tank and the gasiiier which is automatically set bythe latter, substantially specified.

2. In a carbureting apparatus, a gasifier composed of a series of porousrings, intervening porous packings,a su rroundingjacket, and apartition, combined with an air-inlet pipe entering the lower section ofthe gasifier, a gas-delivery pipe entering the upper section of thegasiiier, a gasolene-tank communicating with the upper section of thegasifier, an intervening valve which is automatically set by the latter,and means for counterbalancing the gasifier, substantially as specified.

In witness whereof l have hereunto signed my naine in the presence oftwo subscribing witnesses.
